GEORGE J. PEACOCK, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR OF ONE- FOURTHTO CHARLES BONINI, OF PITTSBURG, PENNSYLVANIA.

ELECTRIC HEATER.

SPECIFICATION forming part of Letters Patent No. 749,628, dated January12, 1904.

Application filed April 19, 1902. Serial No- 103,'725. (N model.)

To (Ll/Z 1071,0717. it may concern.-

Be it known that I, GEORGE J. PEACOCK, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in ElectricHeaters, of which improvement the following is a specification.

This invention relates to certain new and useful improvements inelectric heaters, and has for its object the provision of novel meanswhereby Water-plugs, switches, and the like may be prevented fromfreezing.

My present invention further contemplates to provide a heater that willbe extremely simple in construction, strong, durable, comparativelyinexpensive to manufacture, and highly eflicient in its use.

lVith the above and other objects in view the invention consists in thenovel'construction, combination, and arrangement of parts to behereinafter more fully described, and specifically pointed out in theclaim.

In describing the invention in detail refer ence is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate like parts throughout the severalviews, in which Figure l is a side elevation showing my improved heaterapplied to a water-plug. Fig. 2 is a vertical sectional view of theheater. Fig. 3 is a top plan view thereof. Fig. 4c is a modification.Fig. 5 is a transverse sectional view of Fig. 2. Fig. 6 is a view of oneof the sections forming the interior casing.

In the drawings the reference-numeral 1 represents the Water-plug, and 2the supplypipe, said supply-pipe being surrounded by sections 3, forminga casing. An exterior casing 4, having formed therein partitions 5,surrounds the casing 3, this casing 4 and also the casing 3 beingpreferably constructed of non-conducting material, such as porcelain,glass, gutta-percha, or the like.

The reference-numeral 6 represents a filling of asbestos or likematerial, which is placed between the casings 3 and 4: and also betweenthe partitions 5. Resistance-coils 9 are embedded in this protectiveinsulating material (asbestos) in each of the partitions, these coilsbeing connected by wires 10 to one another and to the binding-posts 8,from which lead Wires 7 to a suitable source of electrical supply.

The operation of my improved device will be readily apparent from theforegoing description, taken in connection with the accompanyingdrawings.

It will be noted that various changes may be made in the details ofconstruction Without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In combination with the supply-pipe of a water-plug, an electricalheating device comprising an inner insulating cylindrical casing adaptedto fit upon the supply-pipe, an exterior casing of insulating materialsurrounding the same, partitions formed integral therewith, saidpartitions being filled with a protective insulating material,resistance-coils placed in each of said partitions and embedded in theprotecting material, said coils being connected one with another,binding-posts carried by the external casing, means electricallyconnecting the coils with said posts and means electrically connectingthe bindingposts with a suitable source of electrical supply,substantially as described.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.
